h1. Question How do I get the Lantronix UDS1100-IAP communicating over DNP?

h1. Answer

Most of the settings can be left at default except for the following:

Under Serial Settings > Pack Controls, Enable Packing needs to be checked off. A small Idle Gap Time will prbably suffice but it might need to be increased if there are radios invovled to accomodate latencies and delays from the radio network. !Lantronix dnp.jpg|border=1!

Under Connection > Endpoint Configuration, the Local Port will need to be set to match the port number of the end device. For example a SP32 would have, by default, DNP in TCP enabled on port 20000. !Lantronix dnp2.jpg|border=1!

If using the Lantronix serial DB25 to DB9 interface, cable part number 297218 can go from the DB9 cable to the RJ45 serial connector on a SCADAPack. In particular, a straight through cable with the TX, RX and Gnd lines is needed.
